1. An apparatus for wireless communication at a first user equipment (UE), comprising:
one or more memories; and
one or more processors coupled to the one or more memories and configured to:
receive, from a base station, downlink control information (DCI) comprising at least one of: an open loop power control parameter, a maximum transmit power, or a closed loop power control parameter, wherein the open loop power control parameter, the maximum transmit power, or the closed loop power control parameter is associated with a physical sidelink shared channel (PSSCH) or a physical sidelink control channel (PSCCH);
reduce a transmit power of a scheduled transmission associated with the PSSCH or the PSCCH to a reduced transmit power if the reduced transmit power is above a threshold or cancel the scheduled transmission if the reduced transmit power is below the threshold, wherein the reduced transmit power is based on the open loop power control parameter, the maximum transmit power, or the closed loop power control parameter; and
measure an interference level associated with a transmission from a high-priority (HP) UE for a period of time, wherein the transmission from the HP UE comprises an overlap with the scheduled transmission, wherein the threshold is based on the measured interference level.
